Answer:
America has industrialize over time.
Explanation:
If we go back in time, we can see the growth of the American people, we went from a hands on agricultural base economy to a machine based economy. We also see a change in women's rights and behavior during the 1920's. As time continues we run into a Great Depression and a Dust bowl causing problems for the rich and the poor. For a long time people of all classes struggle to make a living. Further down the road we have further knowledge of science and even send someone to the moon, this achievement could not have been accomplished back during the depression or even before that. Flash forward to the 2000's we can see all the changes in population and economic development. We have tractors to do the work in the fields, we have more people in charge of politics, we see a change in working classes, we want to send more kids to school to help further their knowledge vs back when women weren't able to go to school, there is a change in the rights people of color and women have, and with all of these changes the growth of America as a whole has changed drastically.
